STANCHION.

SPECIFICATION forming part of Letters Patent No. 389,209, datedSeptember 11, 1888.

Application led July 8, 1888.

To aZZ whom it may concern:

Be it known that I, ABIATHER T. Fara lBROTHER, a citizen of the UnitedStates, residing at Janesville, in the county of Bremer and State ofIowa, have invented new and useful Improvements in Cattle-Stanchions, ofwhich the following is a specification.

My invention relates to improvements in cattle-stanchions, having forits Object to provide suitable and simple means for locking the movablebar thereof in place and also to enable the same to be readily andquickly released when desirable.

The invention consists in a certain novel construction and arrangementofparts for service, fully described hereinafter in connection with theaccompanying drawings, where- 1n- Figure 1 is a perspective view of astanchion embodying my improvements. Fig. 2 is a longitudinal sectionalview thereof, showing the movable bar locked in full lines and Open indotted lines.

Referring to the drawings, Adesignates the rack of the stanchion,comprising the vertical side bars Or posts, c a, the parallel bottombars, b b, affixed at their ends on opposite sides of the lower ends ofthe vertical bars or posts, and the parallel top bars, c c, affixed attheir ends on opposite sides of the upper ends of the said vertical barsor posts. The movable bar D is pivoted at its lower end between theparallel bottom bars, and its beveled upper end operates between theupper parallel bars.

E designates a frame, which is secured to the upper bars of the rack,and consists of the parallel bars e e, arranged across the space betweenthe upper bars Of the rack, and said frame being secured to the rack bydepending ears e e', which are held in place by screws, bolts, orsimilar means. The upper bar, e, of the frame is provided with anaperture, e, in which is mounted the shank fof the latch F, and the headf of the latch operates in an opening, e, in the lower bar, e. A

spring, G, is coiled on the shank of the latch, between the bars e e,and bears at its lower end on the shoulders f 2 f2 on opposite sides ofthe shank at the upper end Of the movable bar D when the latter is inits closed position, as shown in Fig. 2 in full lines.

Serial No. 278,896. (No model.)

On a suitable vertical standard, H, on the upper bar of the frame E, ismounted the operating-lever I, which is pivoted at its end t0 the upperend of the latch, and is adapted, when its free end is depressed, toraise the latch and free the upper end of' the movable bar D, which isthrown by the spring` arm or extension g into the position shown indotted lines in Fig. 2. The lower end of the latch is rounded and theupper beveled end of the movable bar D is provided with a metallicwear-plate, d, whereby, when the latter is swung into its closedposition, the beveled end thereof raises the latch sufficiently to allowthe bar to pass, after which the latch is returned to its normal orengaging position by the spring G. Vhen the operating-lever isdepressed, the movable bar is thrown automatically into its Openposition by the spring arm or extension g.

Having thus described the invention, I claim- 1. In a cattle stanchion,the movable bar D, in combination with the vertical latch F, mounted ina suitable frame, and having the shouldersjmfz, the operating'leverconnected to the latch, and the spring coiled on the latch and providedwith a curved extension or arm adapted to bear at its end against thefree end of the movable bar, whereby the latter is automatically opened,substantially as and for the purpose specified.

2. In a cattle-stanchion, the rack A, and the movable bar D, pivoted atits lower end in the rack and having a beveled upper end, the verticallatch F, 'mounted inopenings in a suitable frame affixed to the rack,the operating-lever mounted on astandard on the said frame and pivotedat one end to the up` per end of the latch, and the spring C, coiled Onthe latch and provided with the curved arm or extension g, integral withthe lower end of the spring and bearing against the free end ofthe bar Dwhen the latter is in its closed position, substantially as specified.

In testimony that I claim the foregoing as my Own I havehereto affixedmy signature in presence of two witnesses.
